Abstract

A battery distribution unit (BDU) for holding a first electronic device having a first blade terminal extending therefrom and a second electronic device having a second blade terminal extending therefrom includes a BDU housing, a strip busbar received in the BDU housing, and first and second cross terminals received in the BDU housing. The first cross terminal receives the strip busbar at a first end thereof and is configured to receive the first blade terminal at a second end thereof. The second cross terminal receives the strip busbar at a first end thereof and is configured to receive the second blade terminal at a second end thereof.

First claim

What is claimed is:

1. A battery distribution unit (BDU) configured to hold a first electronic device having a first blade terminal extending therefrom and a second electronic device having a second blade terminal extending therefrom, the BDU comprising:
a BDU housing;
a strip busbar received in the BDU housing, the strip busbar includes a top edge and a bottom edge extending a length of the strip busbar between first and second ends, the strip busbar having first and second broad sides extending between the top edge and the bottom edge; and
first and second cross terminals received in the BDU housing, the first cross terminal receiving the strip busbar at a first end thereof such that a mating interface of the first cross terminal engages one of the first broad side or the second broad side of the strip busbar between the top edge and the bottom edge and the first cross terminal being configured to receive the first blade terminal at a second end thereof, the second cross terminal receiving the strip busbar at a first end thereof such that a mating interface of the second cross terminal engages one of the first broad side or the second broad side of the strip busbar between the top edge and the bottom edge and the second cross terminal being configured to receive the second blade terminal at a second end thereof.

2. The BDU of claim 1 , the strip busbar having at least two bends along the lengths.

3. The BDU of claim 1 , wherein the first and second cross terminals being mounted to either of the first or second edges at any positions along the length, the first and second cross terminals engaging both the first and second broad sides.

4. The BDU of claim 1 , wherein the strip busbar is formed from a metal coil strip cut to length and bent into a predetermined shape to electrically connect the first and second blade terminals via the first and second cross terminals.

5. The BDU of claim 1 , wherein the strip busbar has a rectangular cross section along an entire length thereof defined by the opposite broad sides, the cross terminals being mounted onto either the top edge or the bottom edge to engage both broad sides.

6. The BDU of claim 1 , wherein the first and second cross terminals include L shaped wall segments arranged in four quadrants, the L shaped wall segments defining a cross shaped cavity configured to receive the strip busbar.

7. The BDU of claim 1 , wherein the first and second cross terminals each include a crossed shaped cavity having a first cavity segment and a second cavity segment perpendicular to and intersecting the first cavity segment, the first and second cross terminals being coupled to the strip busbar at different orthogonal orientations by loading the strip busbar into the first cavity segment or into the second cavity segment of the corresponding first or second cross terminal.

8. The BDU of claim 1 , wherein the first and second cross terminals have open sides at both first ends and second ends thereof allowing the strip busbar and corresponding first and second blade terminal to pass through the open sides.

9. The BDU of claim 1 , wherein the BDU housing includes a channel and chambers open to a channel, the strip busbar received in the channel, the first and second cross terminals received in corresponding chambers to mechanically and electrically connect to the strip busbar.

10. The BDU of claim 1 , further comprising a second busbar and a third cross terminal, the third cross terminal receiving the second strip busbar at a first end thereof and being configured to receive a third blade extending from the second electronic device such that both the strip busbar and the second strip busbar are electrically connected to the second electronic device.

11. The BDU of claim 1 , wherein the first end includes at least four open sides.

12. A battery distribution unit (BDU) configured to hold a first electronic device having a first blade terminal extending therefrom and a second electronic device having a second blade terminal extending therefrom, the BDU comprising:
a BDU housing having an upper housing configured to hold the first and second electronic devices and a lower housing, the lower housing having a top and a bottom, the lower housing having channels extending vertically between the top and the bottom, the lower housing having chambers open to the channels;
strip busbars received in corresponding channels in the lower housing; and
first and second cross terminals received in corresponding chambers in the lower housing, the first cross terminal including a cavity and a protrusion extending into the cavity, the first cross terminal receiving the strip busbar in the cavity at a first end thereof, the protrusion engaging the strip busbar, the first cross terminal being configured to receive the first blade terminal in the cavity at a second end thereof, the second cross terminal including a cavity and a protrusion extending into the cavity, the second cross terminal receiving the strip busbar in the cavity at a first end thereof, the protrusion engaging the strip busbar, the second cross terminal being configured to receive the second blade terminal in the cavity at a second end thereof.

13. The BDU of claim 12 , wherein the strip busbar includes first and second broad sides extending a length of the strip busbar between first and second ends, the strip busbar having a top edge and a bottom edge extending between the first and second ends, the strip busbar having at least two bends along the lengths.

14. The BDU of claim 12 , wherein the strip busbar includes first and second broad sides extending a length of the strip busbar between first and second ends, the strip busbar having a top edge and a bottom edge extending between the first and second ends, the first and second cross terminals being mounted to either of the first or second edges at any positions along the length, the first and second cross terminals engaging both the first and second broad sides.

15. The BDU of claim 12 , wherein the strip busbar is formed from a metal coil strip cut to length and bent into a predetermined shape to electrically connect the first and second blade terminals via the first and second cross terminals.

16. The BDU of claim 12 , wherein the strip busbar has a rectangular cross section along an entire length thereof defined by opposite broad sides extending between a top edge and a bottom edge, the broad sides facing walls defining the channels, the cross terminals being mounted onto either the top edge or the bottom edge to engage both broad sides.

17. The BDU of claim 12 , wherein the first and second cross terminals each include a crossed shaped cavity having a first cavity segment and a second cavity segment perpendicular to and intersecting the first cavity segment, the first and second cross terminals being coupled to the strip busbar at different orthogonal orientations by loading the strip busbar into the first cavity segment or into the second cavity segment of the corresponding first or second cross terminal.

18. The BDU of claim 12 , wherein the first and second cross terminals have open sides at both first ends and second ends thereof allowing the strip busbar and corresponding first and second blade terminal to pass through the open sides.

19. The BDU of claim 12 , wherein the channels and chambers are aligned vertically below the first and second electronic devices.

20. The BDU of claim 1 , wherein the first cross terminal includes a cavity and a protrusion extending into the cavity, the first cross
